The backup system involves inserting the key in a slot or holding it close to a specific space in the cockpit where the energy is transferred to an electric motor. Certain manufacturers have a mechanical key blade that can be used in an emergency situation to open the trunk or to start the car.

Battery Life

Most newer cars come with keyless entry systems and push-button starters. They are controlled by a smart forfour key programming device that communicates with the car via proximity technology.

These devices create their own magnetic field which can affect the fob's transmitter, causing it to run slower. RepairPal reports that the fob may stop working if it is placed too close to the gadgets.

Maintenance
